Abstract: A composite cellular sandwich structure [10]. The structure comprises a cellular core [12] with at least one thermoplastic composite layer [20,22] disposed adjacent to a side of the core and heat bonded thereto. To facilitate bonding, a film of ther­moplastic [24,26] may be disposed between the composite layer and the core. Preferably, the thermoplastic material in both the composite layer and the film is a polyarylene sulfide, such as polyphenylene sulfide. No secondary adhesive is required in the bonding process. A method of substantially continuously producing the composite cellular sandwich structure is also disclosed.

Abstract: The invention relates to the production and use of condensed milk and is characterised in that no stabilisers need to be added. This is achieved by physical means, by heating the starting milk and/or the condensed milk for a prolonged period at a relatively high temperature. The heating of the condensed milk here takes place between a first and a second homogenisation stage, the homogenisation being carried out at a higher pressure in the first stage.

Abstract: An encoder disc for a photoelectric shaft angle encoder includes a disc body (10) which defines first (16) and second (18) regions. The first region (16) is defined between two circles of differing radii (R₁;R₂) and offset centers (22;26) positioned such that the two circles are substantially tangent at one point and the smaller circle is contained within the larger circle. The second region (18) is situated adjacent to the first region (16) and the first and second regions (16;18) have differing light transmission characteristics. The first region (16) forms a measuring track which varies in width substantially sinusoidally around the disc body (10). Especially good results are obtained when the two circles are offset from the central axis of the disc body (10) by substantially equal amounts.

Abstract: An electronic oven temperature regulator employing a comparator (U1B) to control energization of a relay (56,58) for cycling the oven heating unit (gas or electric) in response to comparison of an oven temperature sensor (23) output and a user selected reference temperature about which regulation is desired. A reversible polarity voltage regulator (R5, CR6) provides feedback from the comparator output to the input to provide a positive and negative hysteresis dead band about the selected regulation temperature for minimizing cycling or "hunting" of the heating unit. A fault comparator (6A) tracks the selected reference temperature to disable the heating element relay in the event of a short in the temperature sensor.

Abstract: A flow collector/distributor for a water treatment tank comprises a housing proportioned to communicate through a wall of the water treatment tank to provide flow communication between the tank interior and the tank exterior. The collector/distributor defines an inner end to project inwardly from the tank wall and an outward end to face outwardly from the tank wall. A plurality of slots are defined in the tubular housing, positioned to communicate with the tank interior when the collector/distributor is seated in the tank wall. The slots are of a width which is narrow enough to permit water flow therethrough while substantially preventing passage therethrough of water treatment material present within the tank. One or more one-way valves are provided to permit water flow through all of the slots from the tank interior through the collector/distributor to the tank exterior, but to prevent water flow through some, but not all, of the slots from the tank exterior through the collector/distributor to the tank interior. Also, a novel slot design is disclosed having improved flow characteristics.
